FMB have you actually done a strat raid with 20 sets of buffs and dropped them to <5%? and seen what happens?
(btw thats 42 separate supply runs to get em back up to 100% btw, more if you dont do the city first, then the factories ...)
In my experience people will resupply HQ, but it takes 10mins til everyone notices, another 10mins of explaining on country how it works, and another 10 to resupply if you can get 6 people willing to do it. its rare that an HQ pops again in 10mins. 30mins is more usual. I cant remember seeing anyone resupplying the city strats, although maybe thats a knit thing
The downtime and resupply was balanced perfectly for the old zone system because of the shorter flight time - its pretty much the only bombing I used to do, with repeat sorties to keep the city down - and it had
very noticeable effects when you were trying to take the zone base. people complain about vulching now but its a picnic compared to defending a zone base with no ack for 2h ...
edit: btw yes, that was a hint. bring back the zones!
